This Sundolier robot pumps sunlight indoors for powerful daylighting.

What if you could light your entire building using no electricity, or artificial lights – but just the natural light from the sun? Conventional sky-lights do this well in certain types of single-story spaces, but are not very adaptable, powerful, and often have problems with excessive solar heat gain and heat loss. Enter the Sundolier , a powerful sunlight transport system that’s like putting a solar robot on your roof to pump sunlight indoors! The manufacturer claims a single Sundolier unit can provide enough light to illuminate a 1000-2500 sq. ft. area without any other sources.
